The mast of this tree was made with 2 inch electrical conduit  (The original design was 1 1/4 inch, however that tree blew down in a 2006 storm).  They were joined with a 2 foot piece of steel pipe with a diameter of just under 2 inches OD, and bolted them together with 1/4 inch stainless hardware.  That stood on a 6 foot piece of 1 inch rebar pounded 3 feet into the ground.  It stood by itself, but I didn't trust it until it was guyed.  To tighten the guy wires, we used standard aluminum clothesline tighteners for the lower guys, and turnbuckles for the uppers.  I wanted something easily adjustable here. 

For the base of the tree, we joined 35 feet of 3/4 inch PVC pipe to make a 10 foot diameter circle.  After centering it on the ground around the mast and using it for a guide, we hammered smaller rebar and tie wrapped it to the top at about 3 feet off the ground. (Above right)

Power for the tree was to be greater than 15 amps, so we ran 2 GFCI'd circuits towards the top of the mast. 

This was the original static display.  After computerization, power was delivered by 29 individual extension cords.

  The tree was guyed at about 13 feet in 3 directions.  Next time though, we will guy it at about 9 and 18 feet.  We welded up a plate with 8 angled upwards steel spikes, and a 6 inch piece of pipe downwards.  This fit into the top of the conduit, and was bolted in.

UPDATE:  Again, after the 2006 storm, and tree loss, it now gets guyed at 9 & 18 feet in 4 directions.

  50 boxes of lights ready to go up.  We only used 34 of them, but come this winter, we will fit all 50.   Attaching the lights is then as simple as running from the PVC to a hook, back to the PVC with 2 tie wraps spaced 4 inches apart, and back to a hook.  Every 4th string, do not connect the light ends.  Tie wrap them together, and plug the male end to an extension cord, and to the power bar.  We don't want to see what would happen if all the strings were plugged end to end.

The finished product.  It looks much better in the dark and in person.  Please Email me with any questions.
